WebOrigin of Ciliates. Ciliates belong to the eukaryote supergroup Alveolata (alveolates). These protists are characterized by the presence of unit membrane-bound sacs or alveoli, underlying their plasma membrane (Figure 1 ). There are three major groups within alveolates – the dinoflagellates, the apicomplexans, and the ciliates.
